Why do you use confidence intervals?
Statistical estimates cannot be exact: there is a degree of uncertainty associated with any statistical estimate. A confidence interval is a range such that the estimated value belongs to the confidence interval with the stated probability.

What is statistical estimate?
A statistical estimate is an estimation of population based on one or many data samples of a group. There are two types of estimates: point and interval.
What is a confidence interval?
Answers.com says it is: A statistical range with a specified probability that a given parameter lies within the range. I think that means, just how confident you are that your statistical analysis is correct.
What is the difference between the values on the scale of a graph?
the answer is, interval
2 categorical independent variable and 1 interval dependent variable statistical test?
Two way ANOVA
How do you know when there is a significant difference in statistics?
In statistics, a significant difference is typically determined through hypothesis testing. This involves comparing the observed data with what would be expected by chance alone. If the difference between the observed data and what is expected by chance is large enough, it is considered statistically significant. This is typically determined by calculating a p-value, with a lower p-value indicating a higher level of statistical significance.
What are statistical levels of measurement?
Three basic levels of measurement are nominal, ordinal, and interval/interval-ratio.

The width of a confidence interval is equal to twice the value of the margin of error?
No. The width of the confidence interval depends on the confidence level. The width of the confidence interval increases as the degree of confidence demanded from the statistical test increases.

What is class interval size?
The class interval for each interval is the difference between its upper limit and its lower limit.
Is the Likert scale an interval measurement?
Technically is an ordinal level measurement - because the options imply a hierarchy (i.e low to high levels of your variable of interest), but we cannot say that the difference between each level is precisely the same as you would be able to with an interval measurement. There is some controversy over this though, and it is still often used like an interval measurement in statistical tests, although this might not really be appropriate.
